How can I change Blender's Zoom View to include the Alt key?
If you want to zoom using Alt and holding middle mouse button:


Press CtrlAltU to open User Preferences
Go to Input and find "Zoom"
In the 3D View section, find "Zoom View" and change Ctrl Middle Mouse to Alt Middle Mouse






If you also want to zoom by holding Alt while scrolling the wheel:


Find "Zoom View" item with "Wheel In" / "Out" and add Alt to the shortcut
Disable "Frame Offset" shortcut




Personally, I prefer to getting used to Blender's defaults if possible, as it often fit's the different workflow better.
